IIS Performance

Yesterday we had a little debate in the office about the max number or requests IIS can handle per second. So I did a little research and found that majority of the people are not able to go higher than 300-600 requests/sec, however some claim they were able to get 20000 req/sec. I guess it depends on how much processing work your request does i.e. if IIS is simply returning a HTML page or if it processes ASP.NET page doing authentication, making database requests and constructs the HTML page at the end.

Anyhow, I discovered that IIS 7  has some interesting features wich I was not aware of http://blogs.iis.net/bills/archive/2007/05/07/iis-vs-apache.aspx. I especially like the one that allows you to Troubleshooting Failed Requests Using Tracing in IIS 7.0 http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis-70/.
